BTALING WRAPEER.

Application filed October 2,

To all `zii/0m t may; concern:

Be it known that HERMAN L. GREVE, a citizen of the United States, andresident of New York city, in the county of Kings and State of New York,have invented certain new and useful Improvements in Mailing Wrappers,of which the following is aV specification.

My invention relates to mailing wrappers.

The object of my invention is to provide means for fastening the ends ofa wrapper together at a low cost and in an expeditious manner.

Referring to the drawings which form a part of this specification,

Figure l is a perspective view of a portion of a wrapper shown partly insection, the ends of which are held together by a fastening devicehereinafter referred to as a coupling, and embodying my invention.

Figure 2 is a perspective view of the coupling which l prefer to make ofmetal, and for thin flexible wrappers I prefer to make the coupling ofthin flexible metal as it is easier to perform the operation of couplingthe ends of the wrapper together when the metal is tempered to givespring quality so that the end of the coupling will bend Slightly as itis inserted through the slot formed in the wrapper.

Figure 3 is a perspective view of a modified construction, two hooksbeing formed in place of one as shown in Figure 1.

Figure 4 is a longitudinal sectional view of the Wrapper ends and a sideview of the coupling illustrated in Figure 3.

The drawings are made on an enlarged scale, the coupling being madeabout one quarter the size thereof in practice for use with medium sizedpackages.

A and A indicate the respective ends of a mailing wrapper made of toughpaper, and B, indicates the coupling which is formed by a punch yand dieprocess, and comprises a strip Vof metal embodying a hook B located nearthe middle of the strip and offset therefrom a distance slightly greaterthan the thickness of the wrapper. also prefer to bend the strip to forman offset on a line where the base of the hook B joins the strip asshown. at B2 to permit the wrapperto lay smooth at this point and alsoto act as an abutment for the wrapper and to prevent it from slidingtoward the end A.

The strip B is provided with a tf-shaped end B which is passed throughone end of the wrapper and clinched thereon as illustrated in TFigure l,and therend B4 is passed through a slot C formed in the wrapper, andextends beyond said slot on the innerV side of the wrapper for a shortdistance. noted that the length of the slot C is greater than the widthof the coupling, thus per vmitting the end B4 to .be easily slippedthrough the slot in the act of coupling the ends of the wrapper togetherand permitting it will be the hook B1 to also `pass through the slot andAthen by a reverse movement cause the hook' to engage the edgeof thewrapper as illustrated. Y

In practice the act of coupling the ends of the wrapper together isalmost instantaneous and after they are coupled, the end B4 preventsthem' from becoming easily or accidentally uncoupled, as fa portion ofthe coupling under the Wrapper extends on each side of the slotv C.

The quickness with which the ends may be coupled is a very importantmatter where a large number of wrappers are to be coupled.

As Shown in Figures 1 and 2 the coupling is provided with a single hookindicated by B. In the modified form shown in Figures 3 and 4, the twohooks D and D respectively are shown, formed at each side of the strip Binstead of at the middle thereof, the function however being the same.

Having thus described myV invention, I claim as new:

-l. A wrapper comprising a sheet having a slot therein and a couplingformed of a strip of metal having ahookoffset from the plane surface ofthe strip located between its ends and adapted to passV through the slotformed in said sheet. f

2. A wrapper comprising a sheet havingl a slot therein and a couplingyformed of a strip of metal having a hook offset from the plane surfaceof thelstrip located between its ends and adapted to pass through theslot formed in said sheet, one of the end portions of said strip beingoffset to provide an abut-ment on the strip.

8. A coupling for a mailing wrapper comprising a body portion, an endportion lying in a plane substantially parallel to the plane of the bodyportion and a hook extending beneath the body portion and an end portionextending substantially perpendicular to the body portion. z

4;. A Coupling for a mailing Wrapper com- 5 prising a body portion, anend portion lying in a diiferent plane from the plane of the bodyportion, a, shoulder uniting the body portion to the end portion, a bookextending l from the said shoulder in a different plane 10 from the bodyportion and a V-shaped end Signed at New York city, in the county ofKings and State of New York, this 27th day of August, A. D., 1920.
